Pnctr w fb of r bk wl of thorax w penet thor cavity, subs

This code describes a puncture wound to the right posterior chest wall that has introduced a foreign object and penetrated the thoracic cavity. It specifically indicates a follow-up encounter for this injury, implying ongoing care or assessment after the initial treatment.

Use this code for subsequent visits related to a right-sided back wall thoracic puncture wound with a retained foreign body and intrathoracic penetration. This includes encounters for wound care, monitoring for complications (e.g., infection, pneumothorax), or removal of the foreign body in a delayed setting.

• Ensure documentation specifies "right back wall of thorax" and "with penetration into thoracic cavity."
• The "D" seventh character indicates a subsequent encounter; verify this is not the initial treatment.
• Always code the foreign body separately if it is still present and being addressed.
